Hydrogen cars take a back seat to electric vehicles

Toyota, which has made a big bet on hydrogen-powered cars, is looking more isolated as industry rivals double down on plug-in electric vehicles as the dominant technology in the emerging post-fossil fuel era.

Three years ago, Toyota president Akio Toyoda, grandson of company founder Kiichiro Toyoda, unveiled the Mirai, a four-door family sedan powered by hydrogen tanks and fuel-cell technology that emits nothing but heat and water — and none of the gases that contribute to global warming.

However, sales of the US$57 500 sedan — available in Japan, California and parts of Europe — have yet to break the 5 000 mark, compared to some 300 000 of Nissan’s battery-electric Leaf.

Even hydrogen-car backers such as Honda, Hyundai and Volkswagen’s Audi have refocused their zero-emissions car strategies on EVs

Toyota isn’t the only player in fuel-cell vehicle development. However, even hydrogen-car backers such as Honda, Hyundai and Volkswagen’s Audi have refocused their zero-emissions car strategies on EVs. Investment in hydrogen power stations has been glacial and technology advances have lowered the cost of batteries and extended driving ranges.

China, the world’s biggest car market, nearly doubled the number of charging points last year to 215 000, while the number of hydrogen stations was all of five. It plans to introduce a cap-and-trade emissions policy from 2019, and has joined a growing list of countries seeking deadlines to phase out fossil fuel-powered vehicles.

Tesla this month unveiled a new Roadster with a 1 000km driving range, twice that of Toyota’s Mirai. The electric car maker’s CEO, Elon Musk, has long disparaged fuel cells because of the cost and difficulty of creating, storing and transporting hydrogen.

New entrants

By contrast, the relative simplicity of EV powertrains has helped open the door to a host of new entrants, including vacuum-cleaner billionaire James Dyson. Bloomberg New Energy Finance sees electric cars reaching price parity with their petrol-burning cousins as early as 2025, following a 73% plunge in lithium-ion battery prices between 2010 and 2016.

“It’s easier for companies to make a profit with EV, and it’s easier for governments to prepare the infrastructure,” said Richard Kaye, a portfolio manager at Nippon Comgest. “For the past few years, it’s been EV that’s been gaining traction. Because of that, it’s EV that’s much closer to becoming reality.”

As such, fuel-cell technology is increasingly being put on the back burner. Honda CEO Takahiro Hachigo said last month he thinks EVs will proliferate faster in the near term, and Hyundai executive vice president Lee Kwang-guk said in August that EVs will now be the “mainstay” of the Korean automaker’s eco-car line-up.

Fuel cells were barely a footnote when VW CEO Matthias Mueller announced the group’s aggressive electrification strategy in September.

By contrast, Toyota says its fervour for the technology it began developing in the early 1990s remains undiminished. Fuel-cell and battery-electric vehicles must be developed “at the same speed” because different parts of the world will favour different energy sources based on their specific needs, executive vice president Didier Leroy said in an interview at last month’s Tokyo Motor Show, where Toyota was the only Japanese car maker to display hydrogen-powered vehicles.

“We know, for example, that the fuel cells in the Japanese society will be much more than just cars,” Leroy said. “In many other places in the world, it will be the same.”

Japan has 91 hydrogen stations and is aiming for 160 by 2020 and 320 by 2025. But that’s against more than 28 000 charging points at the end of last year

California is currently the main market for fuel-cell vehicles outside Japan, but has just 30 hydrogen stations. Efforts by Toyota and its partners to set up infrastructure on America’s east coast have been plagued by delays. By contrast, BNEF counted more than 44 000 charging points nationwide in 2016.

Japan has 91 hydrogen stations and is aiming for 160 by 2020 and 320 by 2025. But that’s against more than 2 000 charging points at the end of last year, according to BNEF, whose analysts forecast the high costs and strict regulations governing hydrogen stations will mean the government can only meet 75% of its 2020 goal, and an even smaller proportion of its 2025 target.

“Unlike lithium-ion batteries for electric vehicles, there is no existing parallel industry for fuel cells that accelerates the speed of cost reduction,” said BNEF analyst Ali Izadi-Najafabadi. “Fuel-cell vehicles will not achieve the same level of market penetration.”

The gap is widening even as Toyota forges partnerships aimed at promoting fuel cells. One such global entity established at the start of this year, the Hydrogen Council, said this month that the lightest element could supply a fifth of worldwide energy needs by 2025.

Poor sales

Toyota, which leads FCV sales globally with the Mirai, has only shipped about 4 300 since its launch in late 2014. By contrast, Nissan has sold about 300 000 of the Leaf since 2010 and Tesla has delivered more than 250 000 electric vehicles since the first Roadster rolled out in 2008.

The figures at other FCV makers are even starker: Honda has shipped fewer than 700 of the Clarity Fuel Cell since its debut last year, while Hyundai has moved about 900 of its Tucson Fuel Cell since 2013.

Toyota has set a lofty goal of selling 30 000 FCVs annually by around 2020. Achieving that will need not just more infrastructure, but improvements to the Mirai itself, according to chief engineer Yoshikazu Tanaka. The list he gave echoed what Musk has done with his second-generation Roadster, which on top of a 1 000km range can go 0-100km/h in 1.9 seconds.

First, the Mirai’s range of about 500km under US standards is “not nearly enough”, Tanaka said on the sidelines of a conference in Tokyo last month. The other is more abstract. “We don’t want people to buy the car just for its environmental credentials,” he said. “We have to make it cool.”

Toyota chairman Takeshi Uchiyamada told Der Spiegel in an interview this month that Tesla is not the Japanese company’s “role model”, and that battery-electric vehicles with long ranges are both heavy and too expensive to be mass produced. The new Roadster will be available from 2020 with a base price of $200 000. “Such cars do not fit in our programme,” Uchiyamada said.

Toyota’s immediate priority is to step up development of hydrogen-powered commercial vehicles

In a management reshuffle involving some three dozen people announced Tuesday, Kiyotaka Ise, who heads advanced R&D including FCV and EV development, will become chief executive of group company Aisin Seiki, which makes parts including transmissions and suspensions. His current role will be taken by Shigeki Terashi, an executive vice president and chairman of Toyota’s in-house powertrain company. The changes are aimed at strengthening cooperation among group companies and boosting innovation, according to a statement.

Toyota’s immediate priority is to step up development of hydrogen-powered commercial vehicles, which the company sees as encouraging new filling stations to service them because their largely predetermined routes guarantee revenue. Toyota sold a pair of fuel-cell buses to the Tokyo government at the start of this year, and plans to have about 100 on the road by 2020. It’s also developing a delivery truck for trials with convenience store 7-Eleven Japan from 2019. In California, it’s testing a semi-trailer truck.

“In order to promote our fuel-cell vehicles, we need to promote hydrogen infrastructure,” Toyota senior managing officer Shigeki Tomoyama told reporters at an event to launch a hydrogen project near Tokyo Bay in July. “Commercial vehicles are extremely effective in doing that, so that’s what we want to make.” — Reported by Kevin Buckland and Nao Sano, with assistance from Dana Hull, (c) 2017 Bloomberg LP
